One referring to "Jehovah" as "Jah" (5)
I believe the answer is:
rasta
(Other definitions for rasta that I've seen before include "Member of cult worshipping Haile Selassie" , "Adherent of sect originating in Jamaica" , "Jamaican cultist" , "Dreadlocked follower of Haile Selassie" , "Religious type" .)
